Meaning of the baby name THUNOR.

THUNOR, ÞUNOR.
The Anglo-Saxon form of Old Norse Þorr/Thor, meaning
"thunder."

... Most of the poetical
sources depict Odin as the chief of the gods, as the Allfather of gods
and men, while the prose writings contain frequent indications that
Thor, the Thunder-god (Anglo-Saxon Thunor) stands highest of all
in the popular estimation. There can be no doubt that the Sagas
are right with regard to their own territory. The frequent
occurrences of proper names compounded with Thor (such as Thorolf,
Thorstein, etc.) testifies to his importance in Scandinavia, especially
as we are told that a name compounded with that of a god was esteemed a
safeguard to its bearer... (The Cambridge Medieval History, Bury,
1913)
